.To @ZZ whom t may concern:

Be it known that l, Fermin ALLisoN, a citizen of the. United States, residin@ at @het tanooga, in the county of Hamilton and State of Tennessee, have invented nei' and useful Improvements in lVater-llevating A cation. r

This invention relates to water eleva-ting or pumping apparatus of that type inl which the Water is discharged and elevated alternately from companion tanks or eol'npartments hy the action of compressed air controlled alternately in its passage to the interior of the tanks above the level of the water therein by automatically-operated governorvalve mechanism.

The Object of the invention is to provide water elevating or pumping apparatus of this character having improved means ior more elliciently and positively governing the supply of air to the controlling-valve mechanism and wherein novel means are provided for actuating the controlling-valves at prescribed periods in the operation of the device to shift the governor-valve lor alternately arimitting air to and tanks and for preventing slamming or too abrupt motion of the governor-valve during its shitting movements; also, to generally simpliiy and imprve the construction and increase the practical elliciency of water-elevating apparatus of this character.

In the accompanying drawings, illustrating the invention, Figure 1 is a central von Atical section through the apparatus, showin valve mechanism. as arranged i or admittingair to one of the tanks and exhausting it from the other. Figs. 2 and Barc sectional views through the valves controllingr the 'llow of air to and its exhaust from ythe main or governor valve chest.

Referring now more particularly to the. drawings, A and A represent a pair of vertical tanks or compartments which in practice are arranged helou'the level oil the li id to hc elevated, and B represents a Water or liquid supply pipe having branches B and B communicating, respectively, with the hottom portions oi: said tanks, the ilow of 'water therefrom into the tanks being controlled hy upwardly-f)peiling chock-valves c c. unter-discharge pipe i), loading from the a J- paratus to the poir lo which the water is to he elevated, is also novided with branches D D2, communicating with the bottom porioaratus, oi which the 'l'ollo Wing is a speeiliexhausting it wfrom the l l l i l l l l vleadinfY throuvh the. uioei C TJ e said cavity being so arranged that Whei'i the valve is adjusted in one direction communication will he established between one of the tanks and the valve-chest and between the other tank and the atmosphere or suetion pipe oi an air-compressor through the exhaustport, and the opposite direction. rPhe valve E is con nccted yto or carried by a rod or stern E2, which also carries piston-heads F ll", the inward movements of which are limited 1o stop shoulders or portions f j`/, suitably 'formed Within the chest. An air-supply pipe (1f, lea-:ling from any suitable source of air under pressure, communicates with the chest.

Leading trom the pipe G are pipes H and l l', which respectively extend inte the upper portion ol" the tanks and are connected therein to controlli1ig-valve devices .l l', each censisting' oi a throe-Way vvalve-casing contain lng a rotary valve i. The inlet end oi the 'pipe ll or l l connects with one oi-the branches of the valve-easing in horizontal alineinent pipes J J,.

with the contiguousends ol` the leading lrom opposite ports of the casing through the upper' heads of the tank and to the ends el the valve-chest, pipe J extendinv at its iar end into tue right-hand end cil the chest and the pipe tl .into Athe opposite or leithand end oi the chest.l 'lhc third branch of each casing connects with a vent-pipe 7s heads of the respective tanks to the atniospl ire or to the suction-pipe ol' the air-eoinpresson Each valve i has two operative positions, in one of which it establishes communieation between the pipe ll and the pipe J or the pipe ll and pipo J', as the caso may he, and in the other oi' which it establishes communication he? tween the adjacent pipe J or J, loading to tlie'ai1'-cliest and the vent-pipo 7c or To the stems oi the res lectivo valves are inurmediately connected levers L L, to one arm ol each olwhich is connected a vice versa when adjusted in weielit .,escirm opoiiztion. li', xviii: 'hus be 7c reaf'y undostood that the governor-wlw Wili. be automatically alt-enatoiy shifod for I* '6HL-iii it the supply and exhaust of air to and from the two tanks, so th :it tho Wntoi" f zonmined thm@ cion@ moo bucke', ifi a certain Q* when #no W mice o iii 'ont 'by the Water i.' is; iii
